' Each set bar, hisof a" particular forniation asg'shown inFigure 3,-having on one "'side'a project-ion,l3, thetop, 14,015 which isliorizontal',=the side, 15, vertical and. the bottom, 5,16,; slopingdownwards at an angle of about ---to join the1b'ar. The other side ofeach set baryfl, has arecess, 17,1the top;-18,- of whichlis: horizontal,the side, 19, vertical; and thev bottom, 20; sloping clowning bar, 22,WhlChflS orm'eol 'bya vertical plate having a. number ofsmall horizontal.projections,l23, on its lower edge: one' for, 7 each set bar, whichprojections co-fact with wardsjat the same anglefas fthe' bottom, 16, don the oppositeside, thetwo slopingrportions,

always tend to move away fromthe .projec tions upon theset bars. Thelocking bars arecarried by the frame of the pin-box and are reciprocatedup and down therewith;

the continued descent of the pin-box brings the projections, 23, on thelocking bars in contact. with the sloping portions,.20, and

moves the locking bars to the right in Figure 2, so that theprojections,"25, slide over the tops ofthe projections, 13, on the setbars which have entered perforations, Further descent ofthe pin-box willpress the set bars 1.3, on the set bars. In the bottom: perforatedplate, I, on which the masterrecord rests are situated a' number-ofintermediate pins, 26, the lower upon-the heads,.2,' of the sensing.pins, .1,

through direct contact of the projections, 23,

onlthe locking bars, 22, with the. projections,

ends ofwhich are reduced. in diameter and rest upon the heads, 27 ofpunches,.28,s1tuated in thevpunching-pi'n box, the heads. of

the punches'resting upon ahorizontal plate, 29, attachedto thepin-boxiand forming'a guide, suitable guides, 30 and 31, also beingprovided for the intermediate pins. The

' bottom ends of the punches, 28, are located in the top perforatedplate, J, between which and the bottom perforated plate, J, the blankcards-to be punched are placed. 1 g Each locking bar, 22, is providedwith a locking latch or pawl, 33, pivoted on a rod, 34, secured. to theframe of the pin-box. When a pawl, 33,.is placedinthe portion shownby-dotted lines'it enables any sensing pinsto be cutout from functioningasv for instance the seven pins shown onthe rightof Figure 2. It alsoenables any number of pins to be used. forpunching holes at every strokeof the machine as for instance the live sensing pins shown on the leftof .Figure2. Any combinations of these-two functions may also beobtained.

.Inoperation the cards are between the perforated plates, I and J, andthe upper and lower pin-boxes while the rotation of the eccentric slowlybrings the two pin-boxes down to their lowermost position. As all thepotential rows of perforationsare'sensed the sensing pins, 1, passthrough the holes in thecard and the further descent of the pin-boxmoves the lockingbars, 22, so as to lock these pins intheir downwardposition by means of the sensing pins which have notenteredfperforations in the card, as ex presses them upon the heads ofthe punches which are thus thrust through the cards and perforate themin thedesired position.

Upward movement of the pin-boxes restores the punches to their normalposition and raises the intermediate pins and sensing The sloping partofthe'recessesof the set bars is so arranged that when the pin-box'descends and the two sensing pins which. do not enterperforations restupon the card,

pins'as well asthe set bars,'until in'the final position the lockingbars are restored by the springs, '24, to their normal position, un-

locking the sensing pins which passed through. the perforations by meansof the projections on the locking bars sliding back into the recesses,17, on the set bars. Just before the pin-boxes have attained theirhighest positionthe cards are ejected by means of rolls and are fed intohoppers,

'VandY'a 1 It will thus be seen that a duplicate of the master card isproducedat one single operation and that the sensing pins themselves actto operate the punches directly.

duction of-each master record is produced but any number ofreproductions can be madeby having one or more master records andcontinually feeding them in to the sens ing device. 1

It is to 'be'understood that the invention is equally applicable toproducing Jacquard loom cards, rolls for-piano players or the likehaving perforations.

Having now described my invention what I claim as new and desiretosecure by Lettors-Patent is l. 'Apunching machine'for duplicating aperforated card of the kindindicated, comprising in combination apattern card; a
